A novel mononuclear zinc(II) complex [ZnL(DMSO)] (1) with chelating bisoxime ligand 4,4'-dinitro-2,2'-[ethylenedioxybis(nitrilomethylidyne)]diphenol (H₂L) was synthesized and structurally characterized by X-ray crystallography. The complex crystallizes in the triclinic system, space group P-1, with unit cell parameters a = 8.9730(16) Å, b = 11.9080(18) Å, c = 20.701(2) Å, α = 103.893(3)°, β = 101.975(3)°, γ = 90.029(2)° and Z = 4. The Zinc(II) ion is five-coordinated by four N₂O₂ donor atoms of L^2- and one oxygen atom from DMSO molecule. Interestingly, the unit of cell contains two crystallographically independent but chemically identical mononuclear complexes.
